  1. Load network adapter (if required)

    If you are configuring a DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter, use the "load" command as shown below. CHARON-VAX 3100/96/98 and 4000/106/108 emulations automatically load SGEC (with the name "eza") and therefore no "load" command is required.

    Example:

    load DELQA/DEQNA NIC

              

  2. Load "packet_port" or "tap_port" 

    Load "packet_port" or "tap_port" to connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the host hardware network card (or to a virtual network interface).

    Example:

    load packet_port/chnetwrk NDIS interface = "eth0"

               

  3. Connect the loaded "packet_port" ("tap_port") to the loaded virtual network adapter

    Connect the SGEC, DEQNA, DESQA, DELQA, DEUNA, DELUA, DEMNA, DEBNI or PMADAA adapter to the "packet_port" ("tap_port") by setting the interface name.

    Example: 

    set NIC interface = NDIS

...

The built-in SGEC controller emulator ("eza") has the following parameters that are specified with the "set" command:

interface

Value

"station_address" provides the ability to configure the adapter’s permanent address. By default the adapter’s permanent address is read from the host system’s NIC.

Set the "station_address" when you need to configure a satellite (remotely booted) system that will run DECnet or when the migrated software uses the permanent address on the network adapter.

Format:

XX-XX-XX-XX-XX-XX

XX:XX:XX:XX:XX:XX

Example:

 

set eza station_address="AF:01:AC:78:1B:CC"

rx_fifo_size

Parameterrx_fifo_size
TypeNumeric
Value

"rx_fifo_size" sets the receive FIFO size.

The value is specified in Kb and by default is pre-calculated from the connected port’s size of receive queue.

Typically, you do not need to change the "rx_fifo_size" parameter. It is available for extended tuning and bug hunting purposes.

Example

...

load packet_port/chnetwrk EZA0 interface = "eth0"
set EZA interface = EZA0
set EZA station_address="0C:FE:35:AA:67:3B"

address

Specifies the CSR address. The address must be a valid QBUS and UNIBUS address in I/O space. Initial value is 017774440 which is the factory setting for DEQNA, DESQA and DELQA Ethernet controllers.

Use the address parameter if loading several instances of DEQNA, DESQA, DELQA, DEUNA and DELUA.

"address" parameter value must be unique for every instance of DEQNA, DESQA, DELQA, DEUNA and DELUA.

Example:

load DEQNA/DEQNA XQA address=017774440
load DEQNA/DEQNA XQB address=017764460

load packet_port/chnetwrk <instance-name>

Example:

load packet_port/chnetwrk pp_1

"packet_port" offers several configuration parameters controlling its behavior.

interface

Parameterinterface
Type

Value

interface

Text string

Value

This parameter Identifies an Ethernet adapter of the host system dedicated to CHARON-VAX.

Syntax:

set <name> interface="<adapter>"

Example:

set pp_1 interface="eth0"

port_enable_mac_addr_change

Parameter

port_enable_mac_addr_change

TypeBoolean
Value

If "true" is specified, CHARON sets the appropriate Ethernet address automatically.

If "false" is specified, set the Ethernet address manually. The default value is "true".

Example:

set pp_1 port_enable_mac_addr_change=false

port_ignore_on_rx

Parameter

port_ignore_on_rx

TypeNumeric
Value

The "port_ignore_on_rx" parameter provides the ability to shutdown the port when a specified number of sequential "on receive" errors is exceeded.

Typically, errors on receive indicate serious (unrecoverable) errors.

By default, the value is set to the value of the "port_pending_rx_number" parameter. Value of ‘0’ means infinite.

Example:

set pp_1 port_ignore_on_rx=16

port_retry_on_tx

Numeric
ParameterThe "

port_retry_on_tx

"

TypeNumeric
Value

The "port_retry_on_tx" parameter controls the number of times the port will attempt to transmit the packet before giving up.

By default, the value is 3.

Increasing this value may introduce problems in carrier loosing logic because not all NIC drivers support carrier status query.

Typically, you do not need to increase the value.

Example:

set pp_1 port_retry_on_tx=8

port_pending_rx_number

Parameter

port_pending_rx_number

TypeNumeric
Value

"port_pending_rx_number" parameter sets the number of pending receive buffers.

The default value is 63. The maximum value allowed is 195.

You may want to increase the "port_pending_rx_number" when you have very busy networking and experience problems like losing connections not related to the carrier loss.

Typically, you do not need to change this parameter.

Example:

set pp_1 port_pending_rx_number=128
port

suspend_msg_

...

on_

...

mac_

...

change

Numeric

"port_pending_tx_number" parameter sets the number of buffers the port uses to transmit.

The default value is 62.

You may want to increase the "port_pending_tx_number" value if the log file indicates dropped TX packets due to TX queue overflow.

Typically, you do not need to change this parameter.

Example:

set pp_1 port_pending_rx_number=128

suspend_msg_on_mac_change

Boolean

Parameter

suspend_msg_on_mac_change

TypeBoolean
Value

To avoid confusion arrising from non critical errors during MAC address change, by default, logging is suppressed (default value is "true").

To enable tracing during MAC address change set this parameter to "false"

Example:

set pp_1 suspend_msg_on_mac_change=false
Info

"tap_port" parameters are the same as "packet_port" ones

Example

...

load DEQNA/DEQNA XQA

load packet_port/chnetwrk XQA0 interface="eth0"

set XQA interface=XQA0
